Hi, I develop an Angular5 application and want to use Auth0 authentication.
I need Sign up users via socials like Google, Facebook, Twitter.
I want to use my custom Sign in/Sign up form.
I developed custom Sign in/Sign up via email and password. Sign in via socials developed successfully.
But I don’t understand how can I realize Sign up functionality via socials networks, I can’t find methods for Sign up via socials.
Also, I need to check does user exists in the database at moment of Sign up via socials.
